Class AbstractListModel<E>
java.lang.Object
javax.swing.AbstractListModel<E>
- Type Parameters:
E- the type of the elements of this model
- All Implemented Interfaces:
Serializable,ListModel<E>
- Direct Known Subclasses:
BasicDirectoryModel,DefaultComboBoxModel,DefaultListModel,MetalFileChooserUI.DirectoryComboBoxModel,MetalFileChooserUI.FilterComboBoxModel
The abstract definition for the data model that provides
a
List with its contents.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeans
has been added to the java.beans package.

addListDataListener
Adds a listener to the list that's notified each time a change to the data model occurs.- Specified by:
addListDataListenerin interfaceListModel<E>- Parameters:
l- theListDataListenerto be added
-
removeListDataListener
Removes a listener from the list that's notified each time a change to the data model occurs.- Specified by:
removeListDataListenerin interfaceListModel<E>- Parameters:
l- theListDataListenerto be removed
-
getListDataListeners
Returns an array of all the list data listeners registered on thisAbstractListModel.- Returns:
- all of this model's
ListDataListeners, or an empty array if no list data listeners are currently registered - Since:
- 1.4

-
fireContentsChanged
AbstractListModelsubclasses must call this method after one or more elements of the list change. The changed elements are specified by the closed interval index0, index1 -- the endpoints are included. Note that index0 need not be less than or equal to index1.- Parameters:
source- theListModelthat changed, typically "this"index0- one end of the new intervalindex1- the other end of the new interval- See Also:
-
fireIntervalAdded
AbstractListModelsubclasses must call this method after one or more elements are added to the model. The new elements are specified by a closed interval index0, index1 -- the endpoints are included. Note that index0 need not be less than or equal to index1.- Parameters:
source- theListModelthat changed, typically "this"index0- one end of the new intervalindex1- the other end of the new interval- See Also:
-
fireIntervalRemoved
AbstractListModelsubclasses must call this method after one or more elements are removed from the model.index0andindex1are the end points of the interval that's been removed. Note thatindex0need not be less than or equal toindex1.- Parameters:
source- theListModelthat changed, typically "this"index0- one end of the removed interval, includingindex0index1- the other end of the removed interval, includingindex1- See Also:
-
getListeners
Returns an array of all the objects currently registered asFooListeners upon this model.FooListeners are registered using theaddFooListenermethod.You can specify the
listenerTypeargument with a class literal, such asFooListener.class. For example, you can query a list modelmfor its list data listeners with the following code:ListDataListener[] ldls = (ListDataListener[])(m.getListeners(ListDataListener.class));
If no such listeners exist, this method returns an empty array.- Type Parameters:
T- the type ofEventListenerclass being requested- Parameters:
listenerType- the type of listeners requested; this parameter should specify an interface that descends fromjava.util.EventListener- Returns:
- an array of all objects registered as
FooListeners on this model, or an empty array if no such listeners have been added - Throws:
ClassCastException- iflistenerTypedoesn't specify a class or interface that implementsjava.util.EventListener- Since:
- 1.3
